Hi all!
Here are some good refactorings and new (qemu-img check) checks for
qcow2.
06 qcow2-refcount: check_refcounts_l2(): check l2_bitmap
don't fix unallocated cluster with allocated subclusters (no strong
opinion how to do it correctly)
drop Eric's r-b
keep Kirill's t-b (I believe it still applies, my original task didn't
include error fixing)
define l2_bitmap near l2_entry
add separate assertion and "break;" for QCOW2_CLUSTER_ZERO_PLAIN
others: add r-b: Hanna
Vladimir Sementsov-Ogievskiy (10):
qcow2-refcount: improve style of check_refcounts_l2()
qcow2: compressed read: simplify cluster descriptor passing
qcow2: introduce qcow2_parse_compressed_l2_entry() helper
qcow2-refcount: introduce fix_l2_entry_by_zero()
qcow2-refcount: fix_l2_entry_by_zero(): also zero L2 entry bitmap
qcow2-refcount: check_refcounts_l2(): check l2_bitmap
qcow2-refcount: check_refcounts_l2(): check reserved bits
qcow2-refcount: improve style of check_refcounts_l1()
qcow2-refcount: check_refcounts_l1(): check reserved bits
qcow2-refcount: check_refblocks(): add separate message for reserved
